Stretch cord hook

ABSTRACT

A stretch cord hook includes hook members, connecting blocks and an elastic cord. The elastic cord has its ends secured to the connecting blocks, respectively. Each connecting block is integrally formed with a respective hook member. Each hook member has an inner surface provided with protuberances spaced from each other to prevent it from disengagement.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a stretch cord hook, and more particularly toa hook member having an inner surface provided with protuberances spacedfrom each other to prevent the hook from disengagement.

2. Description of the Prior Art

A conventional stretch cord hook has an open end. The inner surface ofthe hook is a circular and smooth surface. The hook is used to engagewith a truck's body. When the truck is in driving on a rough road, anybumping will cause the hook to slide due to its smooth surface.Sometimes, the hook may disengage from the truck.

SUMMARY OF THE INVENTION

It is the primary object of the present invention to provide a stretchcord hook, which is formed with protuberances for the hook to engagewith the truck body securely.

It is another object of the present invention to provide a stretch cordhook, which provides anti-slip strips on two sides of a connecting blockfor the user to grasp easily.

It is a further object of the present invention to provide a stretchcord hook, which has protuberances each formed with a lower portion andan enlarged head to provide a better grasping force.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

As shown in FIGS. 1 and 2, the present invention comprises hook members1, connecting blocks 2, and an elastic cord 3. The cord 3 has its twoends secured to the connecting blocks 2, respectively. Each connectingblock 2 is integrally formed with a respective hook member 1.

Each hook member 1 has a flat inner surface 11. The inner surface 11 isformed with protuberances 12 spaced from each other. Each connectingblock 2 has two concave sides 21. Each concave side 21 is formed withanti-slip strips 211.

Another embodiment of the present invention, as shown in FIG. 3,comprises hook members 1A. The inner surface 11A of each hook member 1Ais formed with protuberances 12A spaced from each other. Theprotuberance 12A is formed with a lower portion 121A and an enlargedhead 122A extending from the lower portion 121A, which is easy to graspany object.

To practice the present invention, as shown in FIGS. 4 and 5, the hookmembers 1 are linked to a truck's body. The protuberances 12 on theinner surface 11 grasp the truck's body, preventing the hook member 1from disengagement. The two sides 21 of the connecting block 2 areadapted to grasp easily. The anti-slip strips 211 prevent the user'sfingers from slipping.

FIGS. 6 and 7 show another example, the truck's body is provided withrings 4, so that the hook member 1 can be engaged with the ring 4. Theprotuberances 12 hold the ring 4 tightly and prevent it fromdisengagement.

1. A stretch cord hook comprising: hook members, connecting blocks andan elastic cord, wherein said elastic cord has its two ends secured tosaid connecting blocks respectively, each connecting block beingintegrally formed with a respective hook member, each hook member havingan inner surface defining a curved contour, and said inner surface ofeach hook member being provided with a plurality of transverselyextended protuberances, adjacent ones of said protuberances being spacedfrom each other by an arcuate portion of said inner surface extendingtherebetween.
 2. The stretch cord hook, as recited in claim 1, whereineach said protuberance is formed with a lower portion terminating at anenlarged head extending bulbously therefrom.
 3. The stretch cord hook,as recited in claim 1, wherein each said connecting block comprises twosides having a plurality of anti-slip strips formed thereon.
